Cook the pasta according to package directions. Drain when the pasta is al dente.
In the meantime, add the fire roasted tomatoes, Calabrian chilies(using less if you want it less spicy), the raw cashews, non-dairy milk and a pinch of salt to a blender and blend until totally smooth. Set aside.
Once the pasta is done, I like to use the same pot to heat the olive oil on medium high.
Add the shallot and garlic, sauté, reducing heat as needed until the shallot is translucent. About 2-3 minutes.
Add the tomato paste, and then stir into the shallot and garlic.
Pour the sauce you made in the blender into the pot and stir to combine everything. Bring to a simmer, reduce heat to low.
Add the vegan Parmesan and then stir. Taste and adjust seasonings, you will most likely need more salt.
Pour the cooked rigatoni into the pot and toss to combine the pasta and sauce.
Serve immediately with fresh basil if desired.

Notes
*The cashews need to be soaked, either overnight in room temperature water or boiled in water for 15-20 minutes.
